This randomized controlled trial aims to investigate the effects of educational and psychological interventions on the health outcomes of patients suffering from chronic diseases. We recruited 372 patients and randomly assigned them to one of two intervention arms during the trial, which lasted for a year. Both groups participated in a 12-month intervention program, where the intervention group received health education and supportive psychological therapy utilizing virtual reality (VR) technology, while the control group received conventional health education guidance.

Background: Approximately 103 million people across the globe suffer from symptomatic lumbar spinal stenosis, impacting their health and quality of life. The unilateral biportal endoscopic technique is effective for treating single-segment degenerative lumbar spinal stenosis and is seen as a viable alternative to traditional open lumbar laminectomy. However, research on the application of this technique for multilevel lumbar spinal stenosis remains lacking.

Article Synopsis
  • Evaluating tumor radiosensitivity is crucial for predicting treatment success, tailoring plans, and reducing side effects, with mtDNA repair activity serving as a key indicator.
  • A novel DNA-based nanoprobe (TPP-Apt-tFNA) is developed to monitor mtDNA repair enzyme activity specifically in tumor cells by targeting mitochondria, enhancing selectivity and accuracy.
  • The research highlights that tumors with high mtDNA repair activity are less sensitive to radiation, indicating potential challenges in radiotherapy outcomes, thus emphasizing the need for new imaging tools in cancer treatment.

Article Synopsis
  • A new inorganic multilayer barrier film was created on polyethylene naphthalate (PEN) using advanced deposition techniques, combining a SiO layer from ICP-CVD and an AlO/ZnO nanolaminate from PEALD.
  • The resulting film has impressive optical transmittance of 88.1% and low water vapor permeability of 3.3 × 10 g/m/day, demonstrating effective collaboration between the two growth methods.
  • The study indicates that the PEALD layer repairs defects in the SiO layer and the multilayer structure enhances performance, making it suitable for long-lasting organic electronic device encapsulation.

The design and development of highly active non-noble metal electrocatalysts for the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) are crucial for metal-air batteries. In this work, the electrocatalytic performance of different -block metal (PM = Sn, Sb, Pb and Bi) atoms embedded in the g-CN monolayer (PM@g-CN, = 1-3) for the OER and ORR was systematically investigated by density functional theory (DFT). The strong interaction between PM atoms and g-CN substrates indicates the good stability of PM@g-CN catalysts.

Zero-dimensional (0D) halide perovskites have garnered significant interest due to their novel properties in optoelectronic and energy applications. However, the mechanisms underlying their phase transformations and fluorescence properties remain poorly understood. In this study, we have synthesized a micron-scale 0D perovskite observable under confocal laser scanning microscopy (CLSM).

Introduction: Long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) has been shown to be involved in Parkinson's disease (PD) progression, but its mechanism needs to be further explored.

Methods: Mice were injected with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to induce PD mice models, and BV2 cells were treated with lipopolysaccharides (LPS) to mimic PD cell models. MALAT1 expression and suppressor of cytokine signaling 3 (SOCS3) protein level were examined using quantitative real-time PCR and Western blot, respectively.

The abnormal fluctuation of temperature in vivo usually reflects the progression of inflammatory diseases. Noninvasive, real-time, and accurate monitoring and imaging of temperature variation in vivo is advantageous for guiding the early diagnosis and treatment of disease, but it remains difficult to achieve. Herein, we developed a temperature-activated near-infrared-II fluorescence (NIR-II FL) and surface-enhanced Raman scattering (SERS) nanoprobe for long-term monitoring of temperature changes in rat arthritis and timely assessment of the status of osteoarthritis.
